  • a folding unit 20 ( Figures 2-5) and a folding unit 21 ( Figures 6-10) are located at folding stations 4 and 5 respectively, and cooperate with end portion 15 of tubular wrapping 14 to fold end portion 15 onto a relative end of group 12 and so define a wrapping A by forming six flaps 22-27 ( Figure 1), of which, flaps 22-24 are located outwards of major axis 16 with respect to the axis of rotation (not shown) of packing wheel 2, and flaps 25-27 are located between major axis 16 and the axis of rotation (not shown) of packing wheel 2.
  • each of flaps 22-24 is specular with a corresponding flap 25, 26, 27; flaps 22-24 comprise a central flap 23, and two lateral flaps 22 and 24 on opposite sides of central flap 23 and of minor axis 18; and flaps 25-27 comprise a central flap 26, and two lateral flaps 25 and 27 on opposite sides of central flap 26 and of minor axis 18.
  • folding unit 20 at folding station 4 comprises a supporting base 28 fitted with a central folding member 29, an end portion of which is defined by a substantially rectangular plate 30 lying in a plane perpendicular to longitudinal axis 19 of tubular wrapping 14, outwards of the plane defined by the relative end of group 12, and at a distance from said plane smaller than the length of end portion 15 of tubular wrapping 14.
  • Plate 30 is of a width, crosswise to its major longitudinal axis 31, smaller than the length of major axis 16, and is movable - with respect to supporting base 28, in a direction 32 substantially radial with respect to packing wheel 2 and parallel to major longitudinal axis 31, and under the control of a known actuating device not shown - between a withdrawn rest position, in which plate 30 is located outwards of path P in a withdrawn position of non-interference with end portion 15 of tubular wrapping 14, and a forward work position, in which plate 30 interferes with end portion 15 while still remaining outwards of major axis 16.
  • Supporting base 28 is also fitted with two folding arms 33, 34 and a contrast member 35, which, in a direction parallel to longitudinal axis 19, is located between central folding member 29 and conveying pocket 7, and in particular, with reference to the Figure 2 plane, beneath plate 30 and substantially coplanar with the plane defined by the relative end of group 12.
  • contrast member 35 comprises an end portion defined by a plate 36 parallel to and of substantially the same width as plate 30. Contrast member 35 is fitted to supporting base 28 to move, in direction 32, between a withdrawn rest position and a forward work position substantially coincident with the withdrawn rest position and forward work position, respectively, of plate 30.
  • the two folding arms 33, 34 are fitted to base 28 specularly with respect to major longitudinal axis 31, cross over each other at a central portion located between plates 30 and 36, and have respective facing pads 37 on their free ends facing packing wheel 2.
  • the two folding arms 33, 34 oscillate in opposite directions - with respect to base 28 and under the control of a known actuating device (not shown) - about respective axes (not shown) parallel to axes 10, to move respective pads 37 between an open position, in which pads 37 are located on opposite sides of central folding member 29, in a position of non-interference with end portion 15 of tubular wrapping 14, and a closed position, in which pads 37 interfere with end portion 15 and are positioned outwards of major axis 16 and, as explained clearly later on, overlapping plate 36 when contrast member 35 is in the forward work position.
  • folding unit 21 at folding station 5 comprises a supporting base 38 fitted with a carriage 39 powered to move, along guides 40 fitted to supporting base 38, in a substantially radial direction 41 with respect to packing wheel 2.
  • Folding unit 21 also comprises two folding arms 42, 43 fitted to carriage 39 to oscillate in opposite directions - with respect to carriage 39 and under the control of known actuating devices (not shown) - about respective axes 44 parallel to axes 10.
  • Folding arms 42, 43 are positioned specularly with respect to a central plane 45 perpendicular to the Figure 6-10 plane and parallel to direction 41, extend towards packing wheel 2 from carriage 39, and each comprise an end head 46 substantially coplanar with folding arms 33, 34 and bounded laterally by a flat end surface 47 facing packing wheel 2, and by a flat surface 48 facing the other head 46 and forming a right dihedron with flat surface 47.
  • each head 46 is fitted with a bracket 49, the end of which facing packing wheel 2 is connected to a plate 50 defined by a flat, substantially rectangular plate extending from relative head 46 towards packing wheel 2 and the other head 46, and forming a given angle - in the example shown, a roughly 35° angle - with relative flat surface 47.
  • folding arms 42 and 43 are movable between a withdrawn position (shown by the dash line in Figure 10), in which heads 46 are located outwards of path P in a position of non-interference with tubular wrapping 14, and a forward position (Figure 6), in which heads 46 are located inwards of path P and between major axis 16 and a bottom wall of supporting body 8.
  • heads 46 are movable, in opposite directions with respect to central plane 45, between an open position ( Figure 6), in which heads 46 are separated by a distance greater than the length of major axis 16, and a closed position (Figure 8), in which plates 50 are coplanar, and are positioned contacting each other and parallel to major axis 16.
  • folding device 1 Operation of folding device 1 will now be described with reference to one conveying pocket 7, and to one tubular wrapping 14 housed inside conveying pocket 7 with respective end portion 15 projecting from relative group 12 in a direction parallel to longitudinal axis 19.
  • Conveying pocket 7 is fed by packing wheel 2 along annular path P, and is positioned and maintained for a given length of time in a packing position, in which conveying pocket 7 faces folding unit 20, with minor axis 18 of tubular wrapping 14 aligned with major longitudinal axis 31 of plate 30, which is initially set to the withdrawn rest position ( Figure 2) .
  • plate 30 When plate 30 ( Figure 2) is subsequently moved in direction 32 from the withdrawn rest position to the forward work position, it engages and partly folds towards group 12 the central portion of end portion 15 located outwards of major axis 16. Given the distance between plate 30 and the plane defined by the respective end of group 12, the fold made by plate 30 does not result immediately in the formation of central flap 23, but simply pre-folds the portion of end portion 15 corresponding to flap 23, which is not formed until plate 36 of contrast member 35 is subsequently moved ( Figure 3) into the forward work position, before plate 30 is moved back into the withdrawn rest position.
  • folding arms 33 and 34 are moved towards each other, in a direction substantially parallel to said travelling direction 17 ( Figures 3 and 4), into the closed position, engage respective portions of end portion 15 located between major axis 16 and flap 23, and form lateral flaps 22 and 24 by folding said portions ( Figure 4) onto group 12 so as to overlap flap 23 and plate 36,.
  • flaps 22-24 are held folded down on group 12 by an external plate (not shown) extending, parallel to the travelling direction 17 of conveying pocket 7, along a portion of path P interposed between folding station 4 and folding station 5.
  • conveying pocket 7 is positioned and maintained for a given length of time in a position facing folding unit 21, with minor axis 18 lying in central plane 45 of supporting base 38.
  • folding arms 42 and 43 move from the withdrawn position (shown by the dash line in Figure 10) to the forward position ( Figure 6), in which respective heads 46 are located on opposite sides of conveying pocket 7 and inwards of path P.
  • plates 50 When folding arms 42 and 43 are in the closed position ( Figure 8), plates 50 are positioned coplanar with each other, substantially contacting each other end to end, and interposed between the portion of end portion 15 still to be folded and the axis (not shown) of packing wheel 2. And, when carriage 39 is subsequently moved in direction 41 into the withdrawn rest position, plates 50 engage said portion of end portion 15 to form central flap 26 ( Figures 9 and 10) and so complete closure of tubular wrapping 14.
